I m 22 years old, always had safe sex, never had stds I ve been checked many times. Well I ve been in a steady relationship with my gf for 5 months and have sex plenty of times before with no problems. I was only her second. I stayed the night with her 5 nights in a Row and we had sex 4-5 times each night within a matter of 2 hours. On the 2nd day she claimed she had a UTI. Because she s had them before. She smells clean, she taste clean, if it was herpes I would have gotten it on my mouth right? But anyway 4 days later , which was also 4 days ago. After jacking off 2 times I noticed 3 small ulcer like almost bumps or whatever. Blisters even. Really close to each other, one decent size. I ve rubbed my you know what, raw before so I figured I d just calm down and relax and give it a break. Well now there is a blister on the right side (opposite) side of my dick and both of my lymph nodes are swollen. I m so scared I have Herpes or something although it s 92% almost impossible to have gotten it. Please help!
